TIRE FOR VEHICLE-WHEELS.

' Application fled- April 3,

To all whom it may concern:

Be it known that I, ELEAZER KEMPSHALL, a citizen of the United States ofAmerica, and residin r at the Hotel Russell, London,

; V. (1, Eng and, have invented certain new and usefulImprovementsltelating to .Tires for Vehicle-\Vheel's, of which the'following is a specification.

This invention relates. to tires for the wheels of vehicles, andparticularly to tires for the wheels of motor-propelled vehicles, theobject being to provide means which will prevent side-slip or skidding.

The invention may be applied to solid tires, elastic tires comprisingalternate secface thereof, so as to insure an efiicient grip;

but being non-radial to the wheel, they are permitted to give wayslightly under the oad, so as not to interfere with the elasticity ofthe tire.

The accom anying drawings illustrate several forms of carrying out theinvention.

3! Fi ure 1 is a plan view of a portion of a tire s iowingthcapplication of my invention. Fig. 2 is a side elevation of the samepartially in section. Fig. 3 is a transverse sectional view taken infront of one of the metallic sections. Fig. 4 is a view of a slightlydifferent form of my invention. Fig. 5 is a detail view of one of themetallic sections,

shown in Fig. 4.

In carrying out the invention, a number of metallic sections a. areembedded at intervalsin ;a solid tire b. The sections a are providedwith openings e through which the material of the tire passes to form aconnection between the parts. The metallic sections are formed with ears0, which project to the tread surface, so that their edges are flushtherewith; so thatwhen the load comes on the tire-the rubber or otherelastic material between the cars is compressed, and leaves the steelprrfiecting ears free to grip Specification of Letters Patent.

the road surface. The ears are inclined with relation to the tire treadto present an increased area in order to increase the resistance toside-slip or skidding. That isto say, the edge of the section, whenviewed in plan (Fig. 1), appears like a V. The plates a are pivoted at Zto the rim 9, although in 'so nlecases these pivots Z may be dispensedwit a \Vhen applying the invention to the covers of pneumatic tires, themetallic sections a are formed as frames.for instance, as illustratedinFigs. 4 and 5these frames being let into suitable recesses in theouter cover, or molded in the outer cover, for instance, as indicated inFi 4, where the outer cover is denoted by otted lines. These frames maysimply have heels to engage beneath the ill-turned sides of t e rim, orthey may be pivoted to the rim. .It is preferred to make the metallicsecmaterial may be employed.

Having now descrlbed my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In an elastic tire, a number of metallic sections embedded in thetire, and presenting anti skidding edges at the tread surface thereof,said metallic sections being pivoted to the rim, substantially as, andfor the purposes, hereinbefore set forth.

2. In an elastic tire, a number of metal sections having angular-1ydisposed wings embedded in the tire, the edge of each of the wings beingof the same shape as the outer opposite longitudinal surfaces of thetire to form anti-skidding surfaces. 1

number of non-radial metallic sections embedded in the tire andpresenting V-shaped anti-skidding edges at the tread surface.

4. In an elastic tire for vehicle wheels, a number of non-radialmetallic sections, embedded in the tire and presenting V-shapedanti-skidding edges at" the tread surface, said sections being pivotedto the rim.

- 5. An elastic tire for vehicle wheels, comprising alternate elasticand non-elastic sections, and a number of pivotally mounted metallicsections presenting angular edges at -ci1'e tread surface.

6. In combination, a rim, an elastic tire, a number of ietallicanti-skidding sections in the elastic .jrc and pivoted to the rim, saidtions of steel, but any other sufiiciently hard.

3. In an elastic tire for vehicle wheels, a'

metnllm Seetmm having overhanging porj tlOllS embedded in the trend tocause the seetidnst0 roek on their pivots when at load is npblied tn thetire.

7. In an elastic tire, a number of substantially V-shaped metnl sectionseml'mdded in the tire. the edges of the V-F4l1211)0(l sec-tions being:tlnsh with the tire trend and positioned eireinnt erentinlly therewithto pro- \ide anti-skidding surfaces.

8. In an elastic tire, a number of pivotnlly nmunted metallic sectionsembedded in the tire :nnlpresenting anti-skidding edges at the treadsurface thereof.

5). An elastic tire emu )rising at number 0t. metzlllie FPK'tlUllHenlbedt ed in said tire. and

having winged pmtiuns whieh extend to the I surfnee to provide. a Feriesof substantially i V-slniped anti-skidding eurfaees on the the l tread.l 10. In an elastic tire. :1 number of metnllie sections embeddedtherein halving wings embodied in the, tire. and means for pivotnllymounting the sections .in the tire at a point distant from the edgewhere the with: nnt.
